"Let's get out the big car and take a ride around the park to settle our brains," suggested Jack. "I'm all in a whirl!"

Gleefully accepting the proposition, the entire party made for the garage. Jimmie alone pleaded that he was hungry and asked to be excused from the trip. He declared that Wolves were always hungry, especially red-headed ones, and that he would await the boys' return to the club rooms. Accordingly he was left behind.

A ride through the pleasant scenes of Central Park did much to relieve the boys of the strain under which they had been laboring during the earlier part of the day. They were accompanied by their friend the attorney, who thoroughly enjoyed their company.

"We'll have the engine in place tomorrow," Harry announced joyfully, "and then maybe we can plan to take the aeroplane along!"

"It seems to be settled, then, that we shall undertake the mission?" inquired Ned, much relieved to note the attitude of his chums in the matter. "This is volunteer service, remember!"

"Do you think for a minute that we'd see you undertake a trip of this kind and remain quietly at home?" asked Jack, dividing his attention between the car and Ned. "Why, Ned, Old Scout, we couldn't think of such a thing. It's enough for us if you decide to go anywhere. We'll trail along and do what little we can to help!"

"That's the talk, Jack!" declared Harry heartily. "We're with you, Ned, on anything you see fit to undertake!"

"If the 'Grey Eagle' only comes up to our expectations," Ned hesitated, "I'd not be afraid to cross the Atlantic in her!" Then, turning to the attorney, he continued: "The new airship is expected to mark a revolution in aerial navigation. We've been working on it this long time, and tomorrow sees the installation of the engines."

"Yes, sir," gleefully put in Harry, "that little craft has greater lifting power than any aeroplane of which we have any record. It handles better than a Taube or a Voisin or a Curtiss, and we have had a twenty-four-hour trial of her with the old engines while we were carrying nearly nine hundred pounds weight besides we four boys!"
